I am interested in how
natural selection shapes the evolution of social behavior in primates. Most
of my empirical work has focused on the behavioral and reproductive strategies
of female baboons (Papio cynocephalus, P. ursinus). Recent work documents
the adaptive benefits females derive from close social bonds.

I am particularly interested
in questions that explicitly link studies of nonhuman primates to humans.
Experimental work conducted with chimpanzees and children focuses on the phylogenetic
origins and ontogenetic development of prosocial preferences.
